我在ASP.NET Web应用程序中创建了一个单独的文件夹和页面.当我构建解决方案时,我收到错误
The Namespace MyApp already contains a defintion for VDS
这是VDS.Master.cs的内容:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace MayApp{
public partial class VDS : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
这是VDS.Master.designer.cs的内容:

我已经尝试删除VDS.Master.designer.cs文件,但每次构建时都会返回错误.我该如何纠正这个问题？
非常感谢!
您是否有机会从网站将其转换为Web应用程序？我有时会看到转换引起的这个问题.
您的VDS.master文件的第一行可能如下所示:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="VDS.master.cs" Inherits="VDS" %>
至少在我的情况下,问题是它使用的是CodeFile属性而不是CodeBehind.如果你的项目确实是一个Web应用程序并且上面的行包含CodeFile,那么你需要将它改为,CodeBehind所以它看起来像这样:
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="VDS.master.cs" Inherits="VDS" %>
出错的原因是这两个属性的处理方式:
如果您的项目是一个Web应用程序,但它正在使用CodeFile属性,它最终由您编译,然后在运行时编译,导致两个不同的程序集包含相同类的定义.然后一切都爆炸了.
